Mudfish Relocation

Mudfish Relocation

Back in 2009, Kessels Ecology senior ecologist David Riddell, discovered a population of the threatened black mudfish Neochanna diversus within the area of the proposed Rangiriri Section of the Waikato Expressway. A management plan was developed to ensure that this population was preserved during road construction, including temporary relocation of the mudfish and creation of new wetland habitat totalling 300 m2. In June 2013, 394 mudfish were caught over 4 nights in fyke nets and minnow traps. The fish were then housed in outdoor concrete tanks at the University of Waikato—Special thank you to Nick Ling for caring for the mudfish all this time. Now their reconstructed and enlarged habitat at Rangiriri has been completed and the fish will be re-released in early September, 2014. Monitoring is planned for 3 years following release.
